Authors reported a cured case of the cholesteatoma of the paranasal sinuses. The case was that of a 58 years old, male, with chief complains of swelling and pain of the left cheek.The concha of the left nose was atrophic, and the roentogenologic photographs showed that the left maxillary bone was destroyed. At the operation it was observed that the maxillary sinus was filled by cholesteatoma which continously invaded to the posterior ethomoidal sinuses. The left paranaral sinuses were opened, and cholesteatoma was extracted. The disease has never recurred for the period of seven years after operation.Histo-pathologically, the mucous membrane of the maxillary sinus showed the metaplasia of epithelium, and enormous keratinized substance on the epithelial lining. Furthermore the many cholesterin crystals and the foreign body giant cells were observed in the subepithelial layer. But in the mucous membrane of another sinuses, any pathological findings were not found. Therefore, it was considered that the cholesteatoma occured primary in the maxillary sinus, and invaded into the posterior ethomidal sinuses. Stacke reported that the epithelial metaplasia due to atrophic rhinitis was one of the pathogenesis of the paranasal sinuses cholesteatoma. The atrophy of the left nasal concha was observed in this patient, but could not be determined this finding was either cause of the disease or the secondary change followed to cholesteatoma of the maxillary sinus.
